Silicon Optix 50HD 用户手册

This section covers basic Gamma Manager Utility operation. The Gamma Manager
enables you to adjust the light intensity of screen images by adjusting the display
screen brightness display. Gamma correction is also used to make the projector dis-
play match more closely the image from another monitor or other output device such
as a printer.

Note: Before starting the software, make sure that the projector and the
PC are correctly set up, and ensure that the PC and projector are con-
nected. Refer to “Connecting the Projector to a PC” on page 36. 

Click Start, Shortcut to Gamma.exe to open the Gamma Manager Utility.

1. Displays the gamma input/output levels.
2. Enables you to set the gamma curve type:

Exponential: sets the gamma curve based on the function OUTPUT=INPUT

where n is the number selected from the spin box. Use the up and down
arrows to increase or decrease n.
Bézier: sets the gamma curve based on a mathematical formula that assures
continuity with other Bézier curves.

3. Enables you to set the program input signal to that of the projector.
4. Enables you to adjust the red, green, and blue curves or white curves. When

white is selected, red, green, and blue are offset.

5. Press this button to reset all values to the factory default setting.
6. Press this button to transmit the adjusted gamma curve to the projector.
7. Displays program status.
